Unless, of course, one supplies the /DOUBLE keyword to TOTAL()...

I mention this because at least a couple of times (e.g. when doing checksums) I
have wished that TOTAL() also had a /L64 keyword. For example, according to
MACHAR() on my Solaris machine, one loses precision with TOTAL() when totaling
an integer array that sums to more than 2^53, but with a L64 output, one could
sum up to 2^64-1 without losing any precision.
